Hey /sci i disassembled a Lithium battery. what now?
>>8875091
Lick it.
>>8875091
figure a cheap and effective way of increasing it's energy storage capacity.
if you can figure this out, you'll be set for life. rechargeable battery technology hasn't improved in 30 years.

ftfy
>i dot i = -1 instead of 1
if you think the dot product corresponds to scalar multiplication, then either you don't understand vectors, or you don't understand complex numbers.
>>8875086
The real mind fuck is that complex numbers are both vectors (2-d linear objects) and scalars (elements of a field).
>>8875086
>i dot i = -1 instead of 1
Nope.
i dot i is actually 1.
Don't get the complex dot product confused with complex multiplication.
Given a+bi and c+di:
The complex dot product is: ac+bd (and is always a real number).
Complex multiplication is: (ac-bd) + (ad+bc)i
How do you find a log of a number without extensive memorization or calculators?

Mental math.
>>8874863
Monte-carlo estimation, you just generate random numbers, exponentiate and see if it's close to the number you want the log of until you get a good enough estimate.
i have some hydrocloric acid but i don't know its concentration. I wanted to determine it by titration with sodium hydroxide solution, but i don't know how to determine when the pH gets to 7, i have no litmus paper: What can i do?
>>8874764
Post approved.
>>8874764
Not sure if this is bait or not.
:thinking:
as an aerospace engineering undergrad how do I go about getting a job at a high level research facility like area 51 so I can look at ayylmaos?

kek. you have a lot to learn, kid

DoD internships help a lot. The right doctorate program with DoD funding 6.1 work is your foot in the door.
I use it a lot for mathematics, but I'm just wondering how much /sci/ sees it in the real world.
>>8874141
Probably a lot.
Isn't MATLAB an engy language though? Don't mathfags use Haskell or some shit?
>>8874141
I use it as my calculator.
>>8874141
I see engineers talking a lot about it.
How do we improve plastic surgery so that everyone is able to be 10/10s?
>>8874101
Free Plastic surgery training.
By pushing more boundaries with experiments. Everything currently available sticks to "easy" places with varying degrees of success. Stuff like shoulder or rib cage reductions require techniques that haven't been developed yet.
But it's already possible anon. Look at kpop stars.
hi /sci/, can you tell me in wich fields is laplace transform used?

Are most math textbooks written by brainlets?
They are just painful to read. Who the fuck enjoys the autistic style of "definition - lemma - proof - theorem - proof"? Why do only so few authors explain intuition? All the stuff could be understood so much more efficiently if someone took the time to explain why it is defined like that or why a theorem does make sense.
And don't tell me I'm a brainlet for not figuring it out on my own. I usually do, but it just costs a lot of time. The real brainlets are those professors who write a book but don't have the literary or teaching skills to actually present the material in such a way that it will be remembered easily.
>>8873461
what's your background?
>>8873462
Math grad student. After years of studying math I still occasionally develop new intuition on very basic things and I wonder why nobody told me to view it like that before.
>>8873465
well, I think the problem is that intuition is deeply personal. the things that make one person "click" and understand the material aren't the same for anyone. sure, using the correct diagrams and pictures helps, and sure, a few motivating examples will help anyone, but it's highly subjective and what will help one person won't help another one
there's intuition to be obtained no matter the format (def-lem-thm-ex is my favorite) as long as the examples and proof techniques are on point and show the inner workings of what you're trying to explain
Does anyone know the correlation between bits on a computer and atoms? Do they converge at some point that could be used merge the physical and digital world?
>>8873300
How is that /x/ tier?
Bits are voltage levels.

I'm studying for the big brother final.
Since you picked worst winner, looks you'll fail.
I, on the other hand, will get an A+.

How do I self study medicine? What's my path in terms of books/lecture series?
No, I don't want to practice. No, I don't want to self diagnose myself.
I just want to know about it.
>>8869748
Learn Gen Bio, Gen Chem, Organic Chemistry, Biochemistry and Molecular Biology.
Don't forget Physical Chemistry.
Interested in this as well. Any book recommendations apart from the ones in the wiki/sticky?
I see a handful of calculus book paths posted here and then. No biomedical versions?
>Sometimes thought to be anti-democratic, insensitive and elitist, Lindemann supported eugenics, held the working class, homosexuals and blacks in contempt and supported sterilisation of the mentally incompetent.
Is Frederick Lindemann dare I say /ourguy/?
I don't mind soft eugenics (why should future generations be ugly, stupid and miserable just because we dont want to hurt current people's feelings?), but hating groups in general is stupid and wrong.
>>8878148
Sounds like it. It's the way things will be in the future one victor or another.

What do?
I got some books, but what else?

>>8876537
Read up on animal sacrifice.
It'll give you plenty of chances to draw Pentagrams.
